The lamp housing 100 includes a substrate 110 thereon. The illuminator 200 is located on the substrate 110. The illuminator 200 is provided with a plurality of first conductive terminals 212. The fixing device 500 is used to fix the illuminator 200 on the substrate 110, and the fixing device 500 can include a conductive fixing member 300 and a socket 400. Figure 2 is a partial enlarged view of the lamp of Figure 1. As shown in FIG. 2, the illuminator 200 has a side 202, and the first conductive terminal 212 is disposed on the side 202. The socket 400 is disposed on the substrate 110 (see FIG. 1) and corresponds to the side 202 of the illuminator 200. The socket 400 has a plurality of slots 410 for receiving the first conductive terminals 212 removably therein. The conductive fixture 300 includes a rotatable connection structure 310 and an operating rod 320. The rotatable connection structure 310 is received in the socket 400. The rotatable connection structure 310 has a plurality of second conductive terminals 312. The operating rod 320 extends from the rotatable connection structure 310 to the outside of the socket 400 for rotating the rotatable connection structure 310 such that the second conductive terminals 312 abut the first conductive terminals 212. The fixing groove 600 is disposed on the substrate 110 (refer to FIG. 1) for fixing the operating rod 320. Therefore, when the operating lever 320 rotates the rotatable connection structure 310, it gradually approaches the substrate 110, and finally can be fixed to the fixing slot 600.

In the above embodiment, when the illuminator 200 is to be mounted, the user may first insert the first conductive terminal 212 of the illuminator 200 into the slot 410, and then rotate the operating rod 320 so that the rotatable connection structure 310 is The two conductive terminals 312 abut against the first conductive terminals 212 (refer to FIG. 4), so that the illuminators 200 can be electrically connected and fixed. In the above embodiment, when the illuminator 200 is to be removed, the user may first rotate the operating lever 320 to disengage the second conductive terminal 312 from the first conductive terminal 212, and then pull the first conductive terminal 212 away from the slot 410. In addition, the illuminator 200 can be removed in this manner. Therefore, the above embodiment allows the user to quickly and conveniently remove the illuminator 200 without cumbersome procedures such as welding and screw locking.

It should be understood that the term "abutting" as used throughout the specification means that the two elements are in contact with each other to achieve electrical connection and fixed position with each other. . For example, the second conductive terminal 312 is in contact with the first conductive terminal 212, so that the second conductive terminal 312 and the first conductive terminal 212 can be electrically connected to each other, and the first conductive can be positioned. The terminal 212, thereby achieving the effect of fixing the illuminator 200.

It should also be understood that the term "removably inserted" throughout the specification means that the component A can be inserted not only into the component B but also out of the component B, rather than being permanently fixed in the component B. . For example, "first The conductive terminal 212 is removably inserted into the slot 410. The first conductive terminal 212 is not only insertable into the slot 410 but also pulled out of the slot 410.

In some embodiments, the distance d1 between the centers of the adjacent two first conductive terminals 212 and the distance d2 between the centers of the adjacent two second conductive terminals 312 are equal, so that all the first conductive terminals 212 And the second conductive terminals 312 are both capable of abutting. In addition, the distance between the centers of the two slots 410 is also equal to the distance d1 and the distance d2, so that all the first conductive terminals 212 can be inserted into the corresponding slots 410. It should be understood that the "center" of any of the items described throughout this specification is representative of the portion of the article that is symmetrical on opposite sides of the center. For example, the center of the first conductive terminal 212 represents a portion of the first conductive terminal 212 on the left side of the center and a portion of the first conductive terminal 212 on the right side of the center are symmetric.

In some embodiments, the illuminator 200 can further include a plurality of protrusions 210 , each of which is protruded from the side 202 of the illuminator 200 . The first conductive terminal 212 is located on the protrusion 210. The projection 210 can be inserted into the slot 410. The distance between the centers of the two projections 210 and the center of the two slots 410 may be equal so that all of the projections 210 can be inserted into the corresponding slots 410.

In some embodiments, the socket 400 has an opening 420. The operating lever 320 is coupled to the rotatable connection structure 310 and is exposed through the opening 420 to the outside of the socket 400. In other words, the operating lever 320 extends partially from the socket outer 400 into the receptacle 400 to connect the rotatable connection structure 310. In this way, the user can rotate the rotatable connection structure 310 located in the socket 400 through the operating rod 320 exposed to the outside of the socket 400.

In some embodiments, the lever 320 is in engagement with the opening 420. In other words, the operating rod 320 has the same cross-sectional shape and size as the opening 420, so that the operating rod 320 can be in close contact with the inner wall of the opening 420 without a gap. As such, the inner wall of the opening 420 can limit the position of the operating lever 320 so that it does not move arbitrarily (e.g., up and down or left and right). In addition, since the rotatable connection structure 310 is coupled to the operating rod 320, the position of the rotatable connection structure 310 can thus be limited without arbitrarily moving.

Figure 3 is a cross-sectional view of the lamp of Figure 2 taken along line 3-3'. Fig. 4 is a cross-sectional view showing the luminaire of Fig. 3 when the illuminator 200 is fixed. As shown in FIGS. 3 and 4, first, the user can move the illuminator 200 toward the socket 400 such that the projection 210 of the illuminator 200 enters the slot 410. Then, the user can rotate the operating rod 320 (refer to FIG. 2 ) to drive the rotatable connection structure 310 to rotate along with the second conductive terminal 312 to rotate toward the first conductive terminal 212 until the second conductive terminal 312 abuts. After the first conductive terminal 212 is topped (as shown in FIG. 4), the illuminator 200 can be fixed.

FIG. 5 is a perspective view of the luminaire of FIG. 1 when the illuminator 200 is fixed. As shown in FIG. 5, the operating lever 320 can be laid flat on the substrate 110 and fixed by the fixing groove 600. For example, the fixing groove 600 may be formed by a U-shaped elastic seat 610. When the user rotates the operating rod 320 so that the operating rod 320 contacts the U-shaped elastic seat 610, the user can press the operating rod 320 downward to make the U-shaped The elastic seat 610 is slightly expanded outward, and the operating lever 320 is dropped into the fixing groove 600. When the operating rod 320 falls into the fixing groove 600, the U-shaped elastic seat 610 restores the original shape based on its own elastic ability. The operation lever 320 is tightly clamped, thereby realizing the function of the fixed operation lever 320.
